An IoT Privacy-Oriented selective disclosure credential system

Abstract Personal credentials, such as passports and drivers’ licenses, can be implemented electronically using multi-show protocols. In this paper, we introduce an IoT Privacy-Oriented selective disclosure credential system, i.e. based on bilinear pairings multilinear maps. The proposed system consists of three protocols, which allow users to in control their personal credentials. Credentials Authority (CA) verifies attests the Once CA signs these cannot modify any them. Moreover, mask credentials every showing process protect identity from being revealed through a collusion between verifiers. maintains unlinkability issuing Furthermore, it achieves protocol that verifier distinguish user two different sessions protocol. is novel practical terms introducing new supports (Some disclosed others kept secret during protocol.) first utilizes maps identification Making use are suitable for devices have limited capabilities power consumption, key storage, computing power. security analysis discussed Burrows–Abadi–Needham (BAN) logic.
